issue with snow tracks

[newargoowner]

hi, when i rebuilt my machine (1987 8x8), i had to replace the back axles with new ones. the new axles stickout farther than the old ones. about 1 inch (due to the thicker hub). the tracks are catching(rubbing) the inside sidewall of the back tire. is there anything i could do? could i heat up the tracks and bend them out a bit?

I wouldn't alter the tracks sound more like axle issues. What is the part number for the axles you got to replace the old ones? I notice on two argo parts site the axles for my argo have been superseded by the hd axles. I know there is a difference between the older 810-73,75 and the newer hd axles but can't be an inch could it? wold hate to replace six axles for a bent or broken older axle. Back to altering the tracks an inch seems like alot of work and would probably cause alot of wear and tear on tires and tracks.

The new one are the hd i believe. if u go in my photos i have a compare picture of them. the new axles have the tapered ends.

Maybe 1" wheel spacers on the other 6 axles.....or....
Or cut the axle, remove 1" and sleave it and weld it back together.

Good luck

Tim are the HD axles different from the older 810-73,75 axles?

Tim are the HD axles different from the older 810-73,75 axles?

Yes, different....but only because the new axle has a heavier flange....final diamentions are the same and new axle is a direct replacement for the older one.

Now that I think about it, I am wondering if there is a chance that he might of got the inner bearing installed backward which would locate the axle hub slightly farther outward when locked in place??? Inner bearings should all have the bearing collar facing the center of the machine...

Hope this helps, if not, post a couple of pictures and I'm sure that the friends here could help figure it out...

just went and looked at your pictures and found this one....



i think that this axle is even older than the 810-73, because it does not have the tapered inside end that is now used to lock the axle in place and prevent it from sliding out of the machine if the locking bearing collars get lose...i dont have much experiance with machines from that generation and am not sure of the exact retrofit details, but know that it does function the same (only better with the new inner bearing that insures that it will stay in place) so it is just a matter of figuring out what position to install the inner bearing in and shim the axle or bearing flanges if necessary...you might also be able to simply use a couple of the adair hd outer bearing adapter plates to just shim the inner bearing flanges inward as far as you need and then use slightly longer bolts to hold it all in place....each of the adair hd bearing adapter flanges would relocate your inner bearing a 1/4" if used as a shim.....

hope this helps :-)

Thanks for the info. i remeasured and the back axles only stickout about 1/2 inch. I believe the inner bearings set screws are sitting between the inner and outer frame rails. theres a pick in my photos.

I couldn't find the picture, but it sounds like its in backwards and if you just flip it everything will line up perfect ...let us know if this doesn't fix it :-)

/argo-6-and-8-wheelers/p13295-1987-argo. this is the picture. i cant seem to get it to become an attachiment. the set screws are on the outside of the inside rail. from looking at RD axle videos i thought that was the correct way to install the inner bearings. i don't have a washer and bolt going into the new syle axle... do you happen to know what size of bolt to use... fine/course thread... standard or metric ? thanks for the help! i still think there should be enough slack in the tracks to allow for and 1/2 different in tire location. since every tire seems to measure differently. my tires sizes(circumference) at 5psi for the left side from front to back is 70.5, 71.25, 72, 70.25 inches. right side is 70.75, 71.25, 71.75, 70.5 inches. should i change tire locations?

I can not get your attachment to work
Watch my vid again at 1:35, you will see me loosen the Inner Bearing Setscrews. The setscrews are located INSIDE the inner frame rail (Pointing towards the opposite side of the machine)

3/8" Standard Course Thread Bolt. Don't remember how long it is, maybe 1 1/2". Head/Wrench Size 9/16.

I would be tempted to Map your tires. Pick a Circumference, and pressure your tires up to that size. The pressure in the tires is kind of irrelevent, it's better to have all the tires the same size than it is to have them all the same pressure.

thanks RD, The pic is p13295. I took a look at your video. I guess i got the back axle inner bearings in the wrong way. The older bearings all had locking collars and all wear located between the frame rails. Thanks for all the help! if i want to use the tracks i will have to switch the bearings and relocate the set screw locations for the sprockets.

I agree with RD that you could change the size of the tires with air pressure, but if you want to just run them all at the same pressure and keep them soft for a better ride go ahead and put them back on in the staggered position with the smallest in front, next is the largest, then the second largest, and the back one is the second smallest....in my experience this will often make the drive train smoother and quieter and the largest tires in the center also give a slight improvement in ease of turning...JMO

I just re-read your comment and it looks like you attempted to size them correctly already but got the sizes started from the back to front instead of the front to back (unless I misread your comment)... Remember that the smallest is on the front location.....

Best of luck, now go have some fun riding and please share more pictures and videos with all your friends here :-)

Just got gone switching around the inner bearings and drilling out the sprocket set screws (older sprockets set screws are larger than new ones). well it worked. the back tires are maybe 1/8 inch farther out than the rest. that shouldnt hurt anything. RD i see in your video that there are 2 flat washers used with the 3/8 1 1/2 bolt. do you know what size they are? are they both the same size? Thanks tim and RD for all the help!

[newargoowner]

well i got the 3/8 1 1/4inch bolt and flatwashers... but i can't use them due to the fact that the molded floorboard won't fit with the bolt heads sticking out. i don't want to cut up the floorboard. with the inner bearings flipped correctly the floorboard just fits. the older bearings were alot thinner but the new bearings should last alot longer.
